When the prisoner is brought down from Death Row he steps from the elevator directly into a "holding" room that adjoins the witness room. There are two cells in this "holding" room, two, in case it's a double execution. They're ordinary cells, just like this one, and the prisoner spends his last night there before his execution in the morning, reading, listening to the radio, playing cards with the guards.
